Botanical Name: Mentha spicata | Family: Labiatae
Common name(s): Spearmint
Spearmint (and all members of the mint family) has the same medicinal properties as Peppermint. Please refer to that materia medica. Spearmint is milder, however, so may be more appropriate for children.

I have found spearmint to be a delightful addition to tea blends, with its milder flavor.
